GUIDE TO LAKE COUNTY BIRDS DUCKS Northern migration: February–May; Southern migration: October–November. Some ducks are winter visitors to Lake County. NEO-TROPICAL MIGRANTS Spring is a great time to look for members of this group including warblers, vireos, hummingbirds, wrens, thrushes and more. SPARROWS The first to arrive (late March) are song sparrows and white-throated sparrows passing through on their journeys farther north. Sparrows can be seen countywide. Nesting sparrows: MIDDLEFORK SAVANNA* ROLLINS SAVANNA* BLACKBIRDS Male red-winged blackbirds are true harbingers of spring. Other members of this group, such as grackles and cowbirds, follow in April. Red-winged blackbirds are found near marshy areas. Look on the edge of wooded areas for cowbirds. Yellow-headed blackbirds: MIDDLEFORK SAVANNA* ROLLINS SAVANNA* SHOREBIRDS Kildeer: early March; other shorebirds return April–May. Many visiting shorebirds pass by on their trips farther north. This group is hard to spot during dry seasons. WOODPECKERS Year-round: northern flickers and downy, hairy, red-bellied and red-headed; spring: pileated (rare); spring & fall: yellow-bellied sapsuckers.

LAKE COUNTY FOREST PRESERVES 5

For the birds

Providing food for wild birds can be an enjoyable way to welcome wildlife into your yard. Regularly cleaning your feeders will prevent the spread of disease and keep unwanted visitors such as coyotes away. Place hawk silhouettes in nearby windows to deter birds from colliding with reflective glass (download a silhouette at LCFPD.org/hawkshadow). Planting native species of trees, shrubs and wildflowers provides natural food sources best suited to native birds. Visit our annual Native Plant Sale this May to get started—see page 13 for details.

Most people think of migration as a spring and fall phenomenon. In actuality, birds are migrating year-round, some in every season, some for long distances and others for short stretches. Migration is traveling to the right habitat for survival with food being the primary motivation. Photoperiod, the interval in a 24-hour period during which a plant or animal is exposed to light, is the biggest trigger for migration of birds. Since a bird cannot predict the weather hundreds of miles away, the consistent input of photoperiod ensures that seasonal events such as migration happen at the right time. Day-length, and the resulting knowledge of the season, is significant to most animals. In birds, photoperiod not only predicts migration but can provoke changes in feather color, molting, nesting, and even a bird’s song repertoire.

Some birds have specific habitat requirements for breeding and nesting. We take note of these birds because they are good indicators of an ecosys-tem’s overall health. Red-headed woodpeckers, for example, are very choosy and only nest when tree spacing meets their nesting needs. This species is considered in critical decline and in greatest need of conservation. Restoration efforts such as the Woodland Habitat Restoration Project will benefit this species by providing proper nesting habitat. To learn more, visit LCFPD.org/woodland.

Literally millions of birds migrate through our region in the spring and fall along the Mississippi Flyway, which is part of a larger migration route called the Mackenzie Valley-Great Lakes-Mississippi River Valley. The Lake Michigan shoreline is acknowledged as

one of the most important migration routes in the United States for song-birds, but it is simply one section of the greater Mississippi Flyway. Flyways are historic migration routes that provide food, shelter, and a visual north-south orientation. In Lake County, nearly 200 inland lakes and the Des Plaines River Greenway also provide impor-tant migratory stops.

Chances are, there is a fantastic birding spot in a forest preserve near you. For the biggest bang for your birding buck, we recommend Wright Woods (Mettawa), Des Plaines River Trail and Greenway (countywide), Ryerson Woods (Riverwoods), Fort Sheridan (Lake Forest), Independence Grove (Libertyville), Lyons Woods (Waukegan), Middlefork Savanna (Lake Forest), and Rollins Savanna (Grayslake). The chart (facing, left) is a good starting point for birding your forest preserves.
